Stateful Firewall

 

 

Stateful Firewall

Stateful Firewall varies from the IP Filtering Firewall in that it gathers and maintains state information about each session. IP Filtering Firewall examines the packet’s header information and matches it against a set of defined rules. If it finds a match, the corresponding action is performed. If not, the packet is accepted. Stateful firewall intercepts outgoing packets and gathers information from them (for example IP address information, port number) to create state information for that session. When an incoming packet is received, the Stateful Firewall checks the packet against the state information it has maintained and accepts the packet if the packet belongs to the session.

This section describes how to perform the following tasks.
